I don't want to delete duplicate files, but I only want to see one instance of each.
Prioritization among duplicates doesn't matter in this case.
///
The actual scenario:
I want to create a VLC playlist containing every video I have ever downloaded from a particular domain. The files are not well-organized and many exist in more than one location on my computer. Consequently, a Finder search for "Where from" --> [the domain] returns many duplicate files. Which means I can't just drag and drop the search results into VLC without there being many duplicates.
I don't want to deduplicate the files themselves.
How can I make this happen?
